Orange Drop Bag
If you're like we are, there is a good chance that you've left your drop bags plenty of times.
Freezer grade zip locks work pretty good, but sometimes you need a bigger option. So we had some made up custom that are 16" Wide x 20" Tall and made of a 5 Mil, LDPE, orange transparent plastic.
Plus you have your name, bib, checkpoint, and event areas on the bag for easy fill in too.
